Antiskid insulating leather shoes

[0019]Example 1

[0020]A non-slip insulating leather shoe, comprising a sole material and an upper material, the upper material is cowhide; the sole material is made of the following components by weight: 50 parts of modified styrene butadiene rubber, ethylene-tetrafluoroethylene 40 parts of copolymer, 15 parts of hollow glass beads, 6 parts of vulcanizing agent DCBP, 6 parts of diphenylmethane diisocyanate, and 12 parts of foaming agent; the preparation method of the modified styrene-butadiene rubber is as follows: in a polymerizer, Add 3L of cyclohexane-hexane mixed gum solution of soluble polystyrene butadiene rubber, 23g dibenzoyl peroxide and 90g sebacic anhydride, and pass in N2After the reaction is completed, the product is precipitated with anhydrous ethanol, and then dried in a vacuum drying oven for 6h, and finally the product is extracted with anhydrous ethanol for 12h. Put it in a drying box and dry it to a constant weight to make; the blowing agent is a mixture of dinitrosopentamethylenetetramine and 2,3,3,3-tetrafluoropropene in a mass ratio of 1:1 mixture.

[0021]The preparation method of the non-slip insulated leather shoes is carried out according to the following steps:

[0022](1) According to parts by weight, take 50 parts of modified styrene butadiene rubber, 40 parts of ethylene-tetrafluoroethylene copolymer, 15 parts of hollow glass beads, 6 parts of vulcanizing agent DCBP, 6 parts of diphenylmethane diisocyanate, and 12 parts foaming agent, mixed with synthetic raw film;

[0023](2) Put the raw film into the shoe sole mold, apply a pressure of 90 kilograms to the film by a hydraulic press, and vulcanize at 110°C for 12 minutes to obtain the sole;

[0024](3) The upper is made of cowhide, and the sole and the upper are combined by sewing and cutting to make non-slip insulating leather shoes.

[0025]Example 2

[0026]A non-slip insulating leather shoe, comprising a sole material and an upper material, the upper material is sheepskin; the sole material is made of the following parts by weight: 42 parts of modified styrene butadiene rubber, ethylene-tetrafluoroethylene 32 parts of copolymer, 12 parts of barium stearate, 4 parts of sulfur, 3 parts of formaldehyde condensate of sulfonated acetone, and 8 parts of foaming agent; the preparation method of the modified styrene butadiene rubber is as follows: 3L of cyclohexane-hexane mixed glue solution of styrene butadiene rubber, 23g dibenzoyl peroxide and 90g sebacic anhydride, and pass N2After the reaction is completed, the product is precipitated with anhydrous ethanol, and then dried in a vacuum drying oven for 5h. Finally, the product is extracted with anhydrous ethanol for 11h. Put it in a drying box and dry it to a constant weight to make; the blowing agent is a mixture of dinitrosopentamethylenetetramine and 2,3,3,3-tetrafluoropropene in a mass ratio of 1:1 mixture.

[0027]The preparation method of the non-slip insulated leather shoes is carried out according to the following steps:

[0028](1) Take 42 parts of modified styrene butadiene rubber, 32 parts of ethylene-tetrafluoroethylene copolymer, 12 parts of barium stearate, 4 parts of sulfur, 3 parts of formaldehyde condensate of sulfonated acetone, and foam 8 parts, mixed to synthesize raw film;

[0029](2) Put the raw film into the shoe sole mold, apply a pressure of 80 kilograms to the film by a hydraulic press, and vulcanize at 100°C for 15 minutes to obtain the sole;

[0030](3) Sheepskin is used for the upper, and the sole and the upper are combined by sewing and cutting to make non-slip insulating leather shoes.

[0031]Example 3

[0032]A non-slip insulating leather shoe, comprising a sole material and an upper material, the upper material is crocodile leather; the sole material is made of the following components by weight: 60 parts of modified styrene butadiene rubber, ethylene-tetrafluoroethylene 50 parts of ethylene copolymer, 20 parts of calcium carbonate, 9 parts of vulcanizing agent VA-7, 8 parts of nonylphenol polyoxyethylene ether, 15 parts of foaming agent; the preparation method of the modified styrene butadiene rubber is as follows: Add 3L of cyclohexane-hexane mixed glue solution of soluble polystyrene butadiene rubber, 23g dibenzoyl peroxide and 90g sebacic anhydride, and pass N2After the reaction is completed, the product is precipitated with anhydrous ethanol, and then dried in a vacuum drying oven for 4h, and finally the product is extracted with anhydrous ethanol for 16h. Put it in a drying box and dry it to a constant weight to make; the blowing agent is a mixture of dinitrosopentamethylenetetramine and 2,3,3,3-tetrafluoropropene in a mass ratio of 1:1 mixture.
